A stamped stainless steel frame makes the Smith Showdown Polarized Sunglasses light as a feather and surprisingly durable. Did we forget to mention they are comfortable, if so let us say they are extremely comfortable with their temple pads and adjustable silicone nose pads for a comfortable and secure fit. The Smith Showdown shades have a reverse cut lens groove allows these shades to fit perfectly within the classic aviator frame silhouette.
